Update your Java.

 

@AlvinB Im updated to the latest Java -_-

 

The 1.6.0_65 says that you are still running Java version 6.0 update 65. You may be updated to the latest Java but you aren't running your server with it.

 

Hello from a fellow Mac user!

So, here's the problem: You updated your Java but it didn't work *quite* right, so by default everything still runs with Java 6. I have literally the EXACT same problem, so here's what you need to do:

1) Make a file named "StartServer.command" in the same folder as your Spigot/Bukkit JAR file.
2) Paste the following code in:

Show Spoiler Hide Spoiler

Code:

#!/bin/bash
export JAVA_HOME="/Library/Internet Plug-Ins/JavaAppletPlugin.plugin/Contents/Home"
cd "$( dirname "$0" )"
java -server -Xmx2048M -Xms1024M -jar NAME-OF-YOUR-JAR-FILE.jar nogui

3) Change the code where it says "NAME-OF-YOUR-JAR-FILE.jar" to the name of your JAR, e.g. "spigot.jar", "craftbukkit.jar", "spigot-1.10.2.jar" or whatever your JAR file is called.
4) Open up Terminal and type "chmod u+x " (make sure to have a space at the end) and drag "StartServer.command" onto the end of the command.
5) Hit enter.

Explanation: This is just making a small script that changes which Java you're using, and then running the server. If you're uncomfortable using this script or executing the "chmod u+x ..." then just Google it. This script is nothing new. It, or variants of it, have been used for YEARS. The "chmod u+x ..." is just allowing the script file to be executable ("u+x" = for this user, add the executable permission to this file)

I hope this helps!

EDIT: Btw, as far as I know neither of us did anything wrong when updating our Java versions, I think it's a bug in Mac OS X.
